Abstract
OBJECTIVE: The purpose of this study was to determine the prevalence and severity of dental fluorosis in Mexican adolescents.
MATERIALS AND METHODS: A cross-sectional epidemiological study was carried out in 1,024 adolescents 12 and 15-years-old residing in three naturally fluoridated locales at high altitudes above sea level (> 2,000 m or > 6,560 ft) in Tula de Allende, Hidalgo, Mexico. Participants had lived in those communities from birth to their sixth birthday. Both the Modified Dean Index and the Community Fluorosis Index were calculated.
RESULTS: The overall fluorosis prevalence was 83.8 percent. Fluorosis prevalence in El Llano (3.07 ppmF), San Marcos (1.38 ppmF), and Tula Centro (1.42 ppmF) was 94.7, 89.8, and 81.9 percent, respectively. Overall, the Community Fluorosis Index was 1.85. We observed a high prevalence of dental fluorosis–mostly very mild (35.9 percent), but also uncommonly severe (20.6 percent).
CONCLUSIONS: At least 8 out of 10 adolescents had some level of fluorosis, and such prevalence is considered to be a dental public health problem. A relationship between fluoride concentration in water in each community and fluorosis was observed. The high fluorosis prevalence and severity might possibly be associated with the high altitude of the communities.

Assessment of aesthetic perception of mild and moderate dental fluorosis levels among students from the Federal University of Minas Gerais-UFMG, Brazil
PURPOSE: To verify the aesthetic impact of mild and moderate dental fluorosis on young adult students from the UFMG using pictures with different fluorosis levels simulated in a computer program. MATERIALS AND METHODS: The sample consisted of 396 university students, randomly selected from various courses (except dentistry). These participants were

Risk of enamel fluorosis associated with fluoride supplementation, infant formula, and fluoride dentifrice use.
Eight hundred fifty 11- to 14-year-old residents of nonfluoridated communities in Massachusetts and Connecticut, who were born between 1972 and 1975, were investigated in a case-control study of the possible association between enamel fluorosis and exposure to fluoride supplements, infant formula, and/or fluoride dentifrice. The effect of median household income,

Dental and medical practitioners' perception of community water fluoridation as a caries preventive measure.
AIM: To evaluate and compare the perceptions and concerns of dental and medical practitioners towards water fluoridation as a caries preventive measure. METHODS: A self-administered questionnaire comprising 21 questions was designed and validated to assess general knowledge and concerns of fluoride and community water fluoridation (CWF) as a dental caries preventive

Groundwater quality and its health impact: An assessment of dental fluorosis in rural inhabitants of the Main Ethiopian Rift.
Highlights We mapped groundwater fluoride distribution and identified fluoride health risk areas. Dental fluorosis (DF) was evaluated based on TFI scale (Thylstrup and Fejerskov index). Relationship between groundwater fluoride and its dental health impact was established. Effect of milk consumption on DF was evaluated and contributed to reducing DF severity.

Relationship between enamel fluorosis severity and fluoride content
Objectives: Enamel fluorosis is a hypomineralization caused by chronic exposure to high levels of fluoride during tooth development. Previous research on the relationship between enamel fluoride content and fluorosis severity has been equivocal. The current study aimed at comparing visually and histologically assessed fluorosis severity with enamel fluoride content. Methods: Extracted

Racial Disparities in Dental Fluorosis
In 2005, the Centers for Disease Control published the results of a national survey of dental fluorosis conducted between 1999 and 2002. According to the CDC, black children in the United States have significantly higher rates of dental fluorosis than either white or Hispanic children. This was not the first time that black children were found to suffer higher rates of dental fluorosis. At least five other studies -- dating as far back as the 1960s -- have found black children in the United States are disproportionately impacted by dental fluorosis.

Moderate/Severe Dental Fluorosis
In its "moderate" and severe forms, fluoride causes a marked increase in the porosity of the enamel. After eruption into mouth, the porous enamel of moderate to severe fluorosis readily takes up stain, creating permanent brown and black discolorations of the teeth. In addition to extensive staining, teeth with moderate to severe fluorosis are more prone to attrition and wear - leading to pitting, chipping, and decay.

In 1984, a panel from the National Institute of Mental Health (NIMH) warned

Dental Fluorosis Is a "Hypo-mineralization" of Enamel
Teeth with fluorosis have an increase in porosity in the subsurface enamel ("hypomineralization"). The increased porosity of enamel found in fluorosis is a result of a fluoride-induced impairment in the clearance of proteins (amelogenins) from the developing teeth. Despite over 50 years of research, the exact mechanism by which fluoride impairs amelogin

"Mild" Dental Fluorosis: Perceptions & Psychological Impact
The vast majority of research has found that patients, parents, and the general public alike view mild fluorosis (TF score 3) as a significant blemish of the teeth, one that is likely to embarrass the affected child to a degree that cosmetic treatment would be warranted.
